I have a 2008 H1 700 Prowler Arctic Cat. I found a post on here where someone said that it can take 10w-40 or 5w-30. I went to my local shop and all they had what the 10w-40 for wet clutch so I got it. Then I found the service manual for free on the Lawn mower parts website everyone refers to on here. IT says it can only take 5w-30. My question is will using the 10w-40 hurt the prowler or can I go ahead and use it and it'd be fine? Thanks
